Membrane keyboard

Abstract

The invention relates to a membrane keyboard which comprises a membrane provided with printing function symbols and a circuit, a double faced adhesive tape and a base. The membrane provided with the printing function symbols and the circuit and the base are firmly bound together through the double faced adhesive tape. Raw materials are easy to obtain, the structure is simple, the production technology is simple, production cost is low, size is small, thickness is small, weigh is light, key stroke noise is small, meanwhile, dampproof performance, dustproof performance, oil-contamination-resisting performance and harmful-gas-resisting performance are achieved, sealing performance is high, and acid resistance and an anti-seismic function are achieved.

Description

technical field [0001] The invention relates to a computer keyboard, in particular to a membrane keyboard. Background technique [0002] At present, conventional mechanical keyboards used for computers mostly adopt a combination structure of a single key switch. A single key is usually composed of a key body, a keycap, a push rod, a return spring, and a switch reed. Many, the switch maintenance is inconvenient, the overall keyboard is thicker, it looks cumbersome, and it also has a large keystroke noise. [0003] The gaps between individual keys are usually the real gathering places for various types of bacteria and microorganisms, as well as all kinds of garbage, and are difficult to remove. In all sterile places (clean rooms, hospitals, etc.) where the use of computers is often not allowed or limited to a minimum, and in places open to the public (Internet cafes, etc.), this can cause problems such as the spread of corresponding diseases; in electronic experiments Sm...
